Pull request description:
This PR includes changes split from https://github.com/bitcoin/bitcoin/pull/30454. They improve the functional test framework, allowing users to [run individual functional tests](https://github.com/hebasto/bitcoin/issues/146) from the build directory in the new CMake-based build system.
This functionality is not available for out-of-source builds using the current Autotools-based build system, which always requires write permissions for the source directory. Nevertheless, this PR can be tested as suggested in https://github.com/bitcoin/bitcoin/pull/30463#issuecomment-2232618421:
1. Make an out-of-source build:
```
$ ./autogen.sh
$ mkdir ../build && cd ../build
$ ../bitcoin/configure
$ make
```
2. Create a symlink in the build directory to a functional test:
```
$ ln --symbolic ../../../bitcoin/test/functional/wallet_disable.py ./test/functional/
```
3. Run this symlink:
```
$ ./test/functional/wallet_disable.py
```
The last command fails on the master branch:
```

a different error message "socket no message in first %i seconds"
will be displayed if m_last_send=0 or if m_last_recv is 0. make
the test robust by ensuring that they will not be 0 before
bumping mocktime.
The ellswift bytes are computed in the NetworkThread and sent in
the MainThread. Add a `wait_until()` to make sure that ellswift
computation is completed in NetworkThread before sending it in
the MainThread. Also wait until bytes sent are actually received
and use mocktime for more robust disconnection checking.
This test type is represented using SEND_NO_AAD. If AAD of the first encrypted packet
sent after the garbage terminator (optional decoy packet/version packet) hasn't been
filled, disconnection happens.
This test type is represented using WRONG_GARBAGE.
Here, garbage bytes sent to TestNode are assumed to be tampered with and
do not correspond to the garbage bytes which P2PInterface calculated and
uses.
This test type is represented using WRONG_GARBAGE_TERMINATOR.
since the wrong garbage terminator is sent to TestNode, TestNode
will interpret all of the gabage bytes, wrong garbage terminator,
decoy messages and version packet it receives as garbage bytes.
If the length of all these is more than 4095 + 16, it will result
in a missing garbage terminator error. otherwise, it will result
in a V2 handshake timeout error.
Send only MAX_GARBAGE_LEN//2 bytes of garbage data to TestNode
so that the total length received by the TestNode is at max
= (MAX_GARBAGE_LEN//2) + 16 + 10*120 + 20 = 3283 bytes
(which is less than 4095 + 16 bytes) and we get a consistent
V2 handshake timeout error message.
If we do not limit the garbage length sent, we will intermittently
get both missing garbage terminator error and V2 handshake
timeout error based on the garbage length and decoy packets length
which are chosen at random.
Prior to this commit, TestEncryptedP2PState would always
send initial_v2_handshake bytes in 2 parts (as required
by early key response test).
For generalising this test and having different v2 handshake
behaviour based on the test type, special behaviours like
sending initial_v2_handshake bytes in 2 parts are executed
only if test_type is set to EARLY_KEY_RESPONSE.
Early key response test is a special kind of test which requires
modified v2 handshake functions. More such tests can be added
where v2 handshake functions send incorrect garbage terminator,
excess garbage bytes etc.. Hence, rename p2p_v2_earlykey.py to a
general test file name - p2p_v2_misbehaving.py.
random_bitflip function (used in signature tests prior to this
commit) can be used in p2p_v2_misbehaving test to generate wrong
garbage terminator, wrong garbage bytes etc..
So, move the function to util.
